Colloquio
Process of interview on hiring event in Kiev.
1. They schedule time for performing an algorithmic task. You should solve small problem, cover it with unit tests in 1 hour. Some problems are simple, some are more difficult.
2. If you correctly fullfill the task they schedule time for main part: 4 interviews in a set for 45 mins each. No questions on specific language. They are interested only in your understanding of data structures (deep knowledge of hash tables, graphs, lists) and your ability to solve algorithmic problems (problems for uni directional nodes, working with rows of String data, finding paths in matrix and so on), understanding of big-O notation. Database design questions may be asked.
Also they pay attention to your previous experience - you always need to be prepared to answer what was the most excited project, your worst experience, the project where you made great mistakes...
And the give you time to ask them questions about Amazon WS. They listen and fix what and how you ask. And give you quite long and interesting answers.
Surprisingly easy — I expected tougher questions, but the coding round felt more like a warm-up. The main challenge was a DSA problem about counting islands in a 2D grid, which led to a discussion on DFS versus BFS and handling large grids. Funny enough, I had revisited that exact type of question while prepping on PracHub, which made me feel more confident. The interview wrapped up with a behavioral round, and I accepted an offer, but ultimately decided to decline it for another opportunity. Overall, it was a smooth experience.

Domanda 1
Number of Islands — given a 2D grid of '1's (land) and '0's (water), count the number of connected islands. Walk through DFS vs BFS, and discuss how to avoid revisiting cells (in-place mutation vs visited set) and what changes if the grid is huge and must stream from disk.
It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.

Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.

Domanda 1
The first question is LeetCode style algorithms question, and the second question gives a full stack repo (choice of Java, NodeJS, or Django) and asks to solve a backend issue which is causing a bug in the frontend. Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
